QUERCUS MICHAUXII Nuttall. Cow or Basket Oak. (× 1/2.)]

=Distribution.=--Delaware, southern Indiana, Missouri, south to Florida

and west to Texas. In Indiana it is believed that its distribution is

pretty well known and well defined. It is an inhabitant of low wet

woods, although large trees may be found in fairly dry woods which have

been made dry by drainage. In discussing the distribution it must be

remembered that this species was reported as _Quercus Prinus_ before the

sixth edition of Gray's Manual which was published in 1890. Gorby's[35]

reference to Miami County should be ignored, because he compiled his

list of trees from a list of common names to which he appended the

scientific names. His list includes several species which are not

native, and his water willow (_Dianthera americana_) is an herbaceous

plant. Wilson's[36] report for Hamilton County I believe also to be an

error. Wilson preserved no specimen. Since Hamilton County has no cow

oak habitat, and Wilson was not acquainted with the species, I think

this reference should be transferred to the broad-leaf form of _Quercus

Muhlenbergii_. The author has collected and distributed authentic

specimens from a point 2-1/2 miles southwest of Napoleon in Ripley

County. This species is reported by Meyncke for Franklin County as

scarce, and by Collins for Dearborn County. Since the habitat of the

species is found in these counties, it is fair to admit them into the

range of the species. This species is a frequent to a very common tree

in the flats of Clark, Scott, Jefferson, Jackson, Jennings, and Ripley

Counties, where it is usually associated with beech and sweet gum. It is

now known to range as far north as the northern parts of Jackson,

Jennings and Ripley Counties. It is an infrequent tree of the Lower

Wabash Valley as far north as southern Knox County and no doubt followed

eastward along White River. It follows the Ohio River eastward at least

to a point six miles east of Grandview in Spencer County. It no doubt

was an occasional tree along the Ohio River up to Dearborn County. It

has also been reported by Aiken for Hamilton County, Ohio. In the Lower

Wabash Valley it is associated with Spanish and pin oak.

=Remarks.=--Wood and uses similar to white oak. In the flats of

southeastern Indiana it is generally called white oak, and in some

places it is known as bur oak. It grows very rapidly and to a large

size. A tree was measured in 1919 in the Klein woods about 4 miles north

of North Vernon that was 3.57 meters (11 feet, 7 inches) in

circumference, breast high, and was estimated to be 15 m. (50 feet) to

the first branch.

This species when grown in the open forms a large oval head, and in

moist soil would make one of the best shade and roadside trees to be

had. It is not known how it would adapt itself to high ground, but it

is believed this species is worthy a trial as a shade tree. It is

apparently hardy in the northern counties.

=Quercus Bèadlei= Trelease. (_Quercus alba × Michauxii_). This hybrid

between the white and cow oak was found by the writer in 1913 in the

White River bottoms 3 miles east of Medora in Jackson County.

The tree measured 3.54 meters (139 inches) in circumference breast high.

Specimens were distributed under No. 19,037, and the determination was

made by William Trelease, our leading authority on oaks.

=5.= =Quercus Prìnus= Linnæus. (_Quercus montana_ Willdenow of some

recent authors). Chestnut Oak. Plate 44. Medium to large sized tree;

bark dark, tight, deeply fissured, the furrows wide, and the ridges

continuous; leaves on petioles 1-3 cm. long, 1-2 dm. long, obovate to

lanceolate, those growing in the shade usually the widest, rounded at

the base, usually narrowly so or even wedge-shaped, short or long

taper-pointed at the apex, the apex blunt, margins coarsely and nearly

regularly crenate-toothed, the teeth broad and rounded, dark green above

at maturity, a lighter and usually a yellow or grayish green beneath,

only slightly hairy above when young, soon becoming entirely glabrate,

very pubescent beneath when young and usually remaining so until

maturity; petioles, midrib and primary veins beneath are usually

conspicuously yellow, which is a distinctive character of this species;

acorns solitary or in pairs, on short stalks usually about 1 cm. long,

sometimes sessile; nuts large ovoid or oblong-ovoid, 2-3 cm. long,

enclosed generally for about 1/3 their length in a thin cup; scales with

triangular blunt tips, generally somewhat tuberculate and pubescent on

the back; kernel sweet.

=Distribution.=--Maine, northern shore of Lake Erie, to west central

Indiana and south to northern Georgia and Alabama. In Indiana its

distribution is limited to the knobstone and sandstone area of the

State. Its distribution has been fairly well mapped. Two large trees on

the edge of the top of the bluff of the Ohio River at Marble Hill which

is located in the south corner of Jefferson County is the eastern limit

of its range. It crowns some of the ridges, sometimes extending down the

adjacent slopes a short distance, from Floyd County north to the south

side of Salt Creek in Brown County. Its range then extends west to the

east side of Monroe County, thence southwestward to the west side of

Martin County, thence south to the Ohio River. Where it is found it is

generally such a common tree that the areas are commonly called chestnut

oak ridges and are regarded as our poorest and most stony land. In Floyd

and Clark counties it is usually associated with scrub pine. In the

remainder of its range it is generally associated with black jack post

and black oaks. In our area this species is never found closely

associated with limestone, and reports of this species being found on

limestone areas should be referred to _Quercus Muhlenbergii_.
